vss upgarde

[masrawie11]

I'm trying to upgrade 6500 VSS from version 151-2.SY1 to 151-2.SY2.

I checked this link and there are too many ways for the upgrade. Not sure which one is right?

Thanks,

The easiest way to upgrade VSS is by having a maintenance window and perform the following:

1-Copy the new image in both switches

2-change the boot variable to point to the new image

3-Save config

4-reboot both switches at the same time.

It will be all done in approximately 15 minutes.
